MANUFACTURE OF HINGES SPECIFICATION forming part of Letters Patent No.376.702, dated January 1-1, 1888.

Application filed March 24, 1887.

following specification and claim and illustrated in the accompanyingdrawings, in-

which- Figure 1 is a plan view of a blank. Fig. 2 1s a perspective viewof a hinge-section partly formed. Fig. 3 is an end view of twohingesections partly formed. Fig. at is an end view of a hinge. Fig. 5is a plan view of a hinge. Similar letters indicate corresponding parts.

In making the hinge'a blank is formed of suitable material-such, forexample, as sheet metal. This blank may be of a length sufficient tomake, several hinges and a width about equal to twice the required widthof a hinge-leaf. The blank is readily formed by forming, punching, orstamping a suitable strip of material, so as to provide said strip withleaves A, with tongues B, and with apertures O, as seen in Fig. 1, saidtongues and apertures being arranged alternately in a sin- 0 gle lineoccupying the longitudinal center of.

the blank. The strip so formed iscut into suitable lengths, as indicatedby the trans verse dotted lines in Fig. 1. By forming the tongues B andthe apertures 0 respectively 'equa1 to oneanother the several lengths orpieces cut from the said strip of material can be readily madetocorrespond to one another. The pieces cut from said strip are then bentlongitudinally through the central line of al- 0 ternating tongues andapertures,- whereby said pieces or sections are brought to the positionor form indicated in Fig. 2. The tongues B are thereby caused to formthe knuckle of a hinge-section. The tongues B of one hinge- 4 5 sectionare then placed into the apertures O of another hinge-section, and apin,D, Fig. 3, is placed into engagement with said tongues B.

The leaves A A of the respective hingesections are then brought towardone another Serial No. 232,288. (No model.)

or into contact with one another, as indicated in Fig. 4. A hinge isthus formed consisting of leavesswinging about a pin or pintle, D. Asuitable die or press of any well-known construction can be used tobring or press the leaves A A to the position shown in Fig. 4..

The leaves A should be secured to one another by suitable means, such asattaching or fastening devices E. Said fastening devices E may consistof screws or rivets; or other means may be employed to secure the leavesA to one another. Thus, for example, the

leaves A may be welded or soldered together or secured to one another byany suitable means. By making the leaves A symmetrical or equal to oneanother and securing said leaves to one another said leaves willstrengthen or re-enforce one another,thus securing a strong and durablehinge. I r

The hinge can be secured in position by ordinary means, such as screwsor fastening devices passed through apertures F in the leaves A. p r

I am aware that hinges have heretofore been made by cutting from twoseparate strips of metal a number'of blanks or sections of like form,the sections cut from one strip being provided with apertures, andthosecut from the other strip having tongues, then bending each sectiontransversely througlrits tongue or aperture, as the case may be, to

form a knuckle, and connecting the two parts by a hinge-pin withoutsecuring the leaves of each part together. This, however, I do notclaim, and my invention differs therefrom in cutting both parts of thehinge from one strip of metal having a series of alternating tongues andapertures, then bending these sections longitudinally through the centerof said alternating tongues and apertures, and securing the leaves ofeach'part together.

WhatI claim as new, and desire to secure by Letters Patent, is- I Theherein-described method of making a hinge, which consists in providing ablank with leaves A, having a central'longitudinal series of alternatingtongues, B, and apertures C, bending a section of said blanklongitudinally in a line passing through said tongues and apertures,thenengaging the tongues of In testimony whereof I have hereunto set one.section in the apertures of a correspondmy hand and seal in the presenceof two subing section, placing a pin or pivot into en-' scribingWitnesses.
